.. INSERTABLE JOINT.

Application led June 25, 1921. Serial No. 480,294.

To all whom t may concern.'A

`Be it known that I, JOHN J. MEYER, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved InsertableJoint, of which the following is a full, clear, and exact description.

This invention relates to plumbing and has for an object to provide animproved insertable joint for soil pipes and the like wherein a repairjob maybe made with the use of a minimum amount of material and labor. Y

Another `object of the invention is to provide an improved joint forsoil pipesand the like wherein it will be possible to cut off a joint ofpipe now in use and substitute one new section when inserting` a Y, T orother new section.

A still further object of the invention is to provide an insertablejoint for soil pipes and the like wherein means are presented whichVwill present a proper support for the upper part of a soil pipe and atthe same time Aelevate the bottom of the hub to a point adjacent thebottoni of the lower end ofthe upper section of soil pipe.

In the accompanying drawing- Figure 1 lis a side view of part of a soilpipe with certain parts broken away for better illustrating theinvention.

Figure 2 is a fragmentary sectional view showing the part-s as they willappear when an inserted section is being placed in position.V

Figure 3 is a view of the structure shown in Figure 2, but with the hubadj-usted to -its operative position and ready to Ereceive the packingor filling.

Figure 4 is a view similar to Figure 2 but -showing a modified form ofthe invention.

Figure 5 is a View similar to Figure -4 butshowing a slight modifiedconstruction. Referring to the accompanying drawing by numerals, 1 and 2indicate flooring structures of a building through which the sections 3and V4 of a soil pipe extend. If, for any reason, it should be necessaryto remove the section 4 and place a new section in place, an entire soilpipe must be taken down and a new one substituted or one or more of thesections of pipe broken and removed and a joint supplied in addition t0the new section 4. In the construction shown in Figure 1, the section 5indicates the new section provided with a joint at the upper end wherebyit cooperates with the old section 6 previously secured to section 3.The section 4 may be readily set into the hub 7 ofsection 8 by merelyplacing the same correctly in position and then providing suitablepacking for the hub. However, the section connecting section 4 andsection 6 cannot be of the ordinary type as the hub of an ordinarysection could not be properly fitted over the section 6 and' thenlowered into the hub 9 of sectionr4.

To obviate this difiiculty, a special insertable joint is provided inwhich section 5 is used, which section is a straight tube having andthen swung over to a position beneath c the nipple 12. The hub 11 isthen lowered and screwed onto the` threads 10 and the joint is incondition for receiving packing which may be a fibrous filling 15 andthen the lead filling 16 or may be of any other suitable material.

Figure 3 shows the parts ready for the filling and Figure 1 shows'theparts 'after the filling has been inserted. This construction presents atight connection and at the same y,time provides a `support for thesection 6 and other sections bent the same. In Figure 3 an aperture isprovided in the hub 11 which is normally closed by the plug 17, s aidaperture acting as an inspection opening, to ascertain if there is acontact between the pipe 6 and nipple 12. If desired, a second aperturemay be provided in the hub 11 for receiving an auxiliary vent o r drainpipe 18 or if this pipe is not needed the plug Ycan .be inserted forclosing ythe opening. An opening 18 is also provided in thenipple l2 soas to provide a free communication between the pipe 18 and the interiorof the nipple. By providing the flange 14, it will be noted that theeective In order to raise the' bottom of the hub is raised tosubstantially threaded bore portion 25.

`ranged above the joint.

the same plane as the bottom of section 6 whereupon the filling l or thelead filling 16 cannot move through the nipple of section 6. v

In Figure 4i, another form is provided in which thejnipple is formedinto a ring 22 having a less internal diameter than section 6 and also aless external diameter though the walls of the ring are of the samethickness and, therefore, present a proper support for section 6 andtheother sections oic pipe above said section. The bell 23 is used withthis form of the invention, which bell is provided with a raised bottom24 and a When the section 5 is being inserted, the threaded portion 25is screwed upwardly until it is opposite the ring 22 whereby the section5 may be readily inserted and then the hub is screwed down onto thesection. As the shoulder 24 overlaps the lower end of section 6 afterthreads 25 have engaged pipe 5, the parts are properly bent `togetherand aligned so that the packing may be readily inserted, which in thisinstance may be lead alone or fibrous packing with the lead on top ofthe same.

Figure 5 shows a form ot invention similar to Figure 4;. rlhe bell 26 isprovided with an upstanding liange 27 instead of the raised shoulder 24,which flange acts as means :tor centering the ring 22 andliolding thesame in place when the bell is screwed down onto section 5 asillustrated in the drawing.

ln all forms of the invention, some form of supporting ring structure isprovided which will act as a nipple or spanning ring and at the sainetime will act as a permanent support tor the sections oi pipe art willalso be noted that in all forms of the invention, the hub is adjustableso as to readily permit the insertion of the lower pipey section '5 andthen 'act as means for locking said section against lateral movement.

It is understood that the hub bottoni may be modified and elevated asshown in'Figure 5 so as to bring the hub bottom and pipe end 6 on thesame plane or the hub bottom above pipe end 6 to cause a properalignment thereof.

lt will be noted that the spacer ring or Arings form a false hub'bottom.rThe rings may be arranged solid as shown in Figure i though this is notabsolutely necessary as a flange structure similar to that shown inFigure 2 may befused, the straight hub allowing ree movement over saidnipple or ring for engagement or disengagement with the pipe section 5.In any of thetorms of the invention, the hub bottom may be placed at anypoint between pipe end 5 and pipe 6 to meet Iall conditions.

It is to be understood that a pipe having branch openings or the usualstrengthening bead at the end opposite the threaded end of pipe section5 is to be considered uniform in diameter throughout as well as anordinary straight pipe within the meaning of the specification andclaims as these features have nothing to do with the 'functioning oitthe threaded end.

What I claim is z- Y l. An insertable joint for soil pipes and the likecomprising two pipe sections of uniform diameters, a tubular nipple ofless exterior diameter than the said two pipe sections inserted betweensaid pipe sections, and a hub adapted to form a water tight joint aroundthe ends of the two pipe sections and nipple, one end of the hub beingadapted for a filler joint, the other end being contracted andinteriorly threaded to screw upon the threaded end of the other pipesection, the contracted end of said hub being capable of telescopingover said nipple and movement of said nipple being limited by thesuperimposed pipe section.

2. An insertable joint for soil pipes and the like, comprising a pipesection having threads at the upper end, a tubular supporting andspacing sleeve having a longitudinal portion of slightly less exteriordiameter and a Flange portion of greater exterior diameter than theexterior diameter of said pipe section, a removable hub having aninwardly extending threaded portion adapted to be screwed onto saidthreaded section when in use and when said threaded section is beinginserted to telescope over the smaller portion' of said sleeve by reasonof the reduced diameter of said smaller portion, said sleeve to rest onthe end of the pipe section.

3. An insertable joint Jfor soil pipes and the like, comprising two pipesections, tubular nipple of less exterior diameter than the said twopipe sections inserted between said pipe sections, and a hub adapted toform a water tight joint around the ends of the two pipe sections andnipple, one end of the hub being adapted for a filler joint, the otherend being contracted and interiorly threaded to screw upon the threadedend of the other pipe section, the contracted end oit said hub beingcapable oi" tclescoping over said nipple and movement of said nipplebeing limited by the superimposed pipe section.
